single-replacement reaction
One element takes the place of another in a compound.
Electrons are nice.
I'd venture to say the electrons themselves. They're so small they don't even exist in a concrete place, they are just in a cloud of places they could be. The nucleus is amazingly small compared to the size of the whole atom, but it still has weight, mostly unlike the electron.
to obtain an element from its compound it is necessary to cause a chemical reaction to take place
A higher place in the periodic table of the elements.
Mexico gains independece from Spain
It is changing he element that is a liquid from a liquid to water vapor. A gas.
When a physical change takes place, a certain element or chemical will change its shape and in many cases, the volume too. Water takes the shape of the mold casing once it freezes.
It is called the trough.
solid
Extra ordinary gains is shown in income statement of the company and it is not shown in the balance sheet of the company.
Energy - usually heat energy causes a solid to turn to liquid.
In hetrogeneous reactions (where the reactants are in different states) the size of the particles of a solid may change reaction rate, since the surface is where the reaction takes place, and the surface area is increased when the particles are more finely divided. In general, the smaller the particles the faster the reaction
A reaction when a free element or ion takes the place of and element or ion in a compound is called a single replacement reaction
There are quite a few social gains that have recently happened for women. One of these recent gains was equal rights in the work place.
